The Brackley team completed another one-two in Canada with Lewis Hamilton taking victory from Nico Rosberg to consolidate Mercedes’ lead in the drivers’ and constructors’ championships.

But Wolff said: “Coming away with another top result in Canada, it would be easy to sit back and think we’ve got everything under control. But in reality, this is never the case.

“Not only did that race require a careful balancing act from the pit wall and from the drivers but we also saw that there is more to come from our competitors, even if maybe it wasn’t clear from the result.

“There must be more to come from ourselves if we are to continue this good form and Austria will provide a tough test. We had a challenging weekend there last year and fully expect another close competition this time around.”

Hamilton said: “It was a great feeling to finally get back on top in Canada. Now, though, it’s time to move on and put things right at a circuit I had a tough introduction to last year, Austria.

“Of course, I’ll be working hard to have a clearer shot at the win on Sunday.”

Rosberg added: “Canada was really lost for me on the Saturday. Not getting everything together in qualifying hurt my chances big time but I had the pace and that’s a big positive to take forward and go maximum attack in Austria.

“My first race at this track last year couldn’t have been much better. I’m sure we’ll have some tough competition here once again with Williams and probably some others too.”

Lotus F1 Team driver Romain Grosjean reckons he and team-mate Pastor Maldonado are better placed for this year’s race in Austria for the Enstone outfit.

Grosjean said: “We have a lot more potential to do well this year. Last year was the first time at the track for Formula 1 in over a decade and we were doing a lot of learning of the circuit and set-up.

“We didn’t have the right package for our brakes so it was a frustrating weekend. This year we should be much better placed and I’m looking forward to being able to attack the track.”
